BUTTON.

SPECIFICATION forming part of Letters Patent N 0. 535,031, dated March 5, 1895.

Application filed November 10, 1893. Seria1No.4=90,567. (No specimens.) Patented in Germany May 12, 1891, No. 60,950, and in England June 9,1891,No. 9,775.

' which a patent was granted in Germany May 12, 1891, No. 60,950, and in England June 9, 1891, No. 9,775,) of which the following is a specification.

This invention relates to certain new and useful improvements in clothes buttons and has for its object to provide a button composed of several parts which shall presentcertain novel and useful features, all as will be hereinafter fully set forth.

The novel features of my invention will be carefully defined in the claims.

In the accompanying drawings which serve to illustrate my invention :Figure 1 is a face view of the blank from which the base plate of the button is formed up, and Fig. 2 represents in plan and transverse section, the capplate of the button. Figs. 3 and 3 represent the said base plate in various stages of the manufacture of the button and Fig. 4 shows in plan and transverse section, a shield or cover plate which may in some cases be used to cover the under side of the base plate. Figs. 5, 6, 7, 8, 9, 10 and 11 show various modified forms of the button in accordance with my invention, and Fig. 12 is a detail view showing the shank of the button.

Thelower part or base of the button is made of a specially shaped metal disk E of the form seen in Fig. 1. The circumference of this disk, instead of forming a complete circle has a number of equidistant projections e, e, e 850., each of which is bounded by a short curve f, f, f &c., said curves being of such size and shape, that they form together a complete or almost complete circle, having approximately the diameter 6 of the shank or pin of the button. In the form shown by Fig. 1, there are six radial projections. Consequently each of the said short curves f, f, 850., forms one-sixth of a circle, and its length d is approximately 5. This metal disk, shaped as described is now provided with-cuts or slits extending from the base of the said projections 6, &c., toward the center as indicated by the dotted lines in Fig. 1, and the segments e',fo' d, 6 f c d, 6 f c 01 thus produced are turned inward around their respective bases 0 d, c d, 0 d (be, as indicated 'by the dotted lines in Fig. 3, until their curved ends meet or are close together and form a circular opening of the diameter 8. Theconnection with the shank and counterplate of the button represented in Fig. 12 detached, may now be made by pushing the head of said shank through the central opening seen in Figs. 3 and 3' thereby pressing apart the segments e f, e f', &c. When the head of the shank has passed through the opening the segments will snap back again owing to their elasticity.

The head of the shank may be pointed as seen in Fig. 12 in order to pierce the cloth to which the button is to be secured.

In the center of the base plate a supporting ring of cylindrical or conoidal shape (Figs. 3 and 3') is formed by bending up the inner edge of the same, in such a manner that it supports the segments close to their curved extremities ef,e f',e f ,&c. Consequently, when the shank is being drawn up or tightened, the segments efc' d, 6 f o d, e f 0 (1 &c., cannot continue to turn on their bases 0' d, c d, 850., because they rest on the edge of the supporting ring. The six intermediate segments a. b c d, a b 0 cl, &c., remain at disposal and maybe utilized in various ways. The bases of each pair of segments depend upon each other as regards their length, so

that by widening the base of one segment, that of the adjoining segment will be narrowed by the same amount. For instance in Fig. 3, the bases of the segments 6' f 0" cl, c f 0 cl, c''f 0 d &c., are narrow, while the bases of the segments a b o d, a b c d, dire, are wide.

In Fig.7 the segments a b c d, a b c d, 850., have shorter bases, and the segments 6 f 0' cl, e 0 d, 850., have wider bases.

Figs. 5, 6, 8, 9, 10, and 11 show various methods or means of connecting the segments a b c d, a b c d, &c., with the upper plate or button top, or with a second base plate.

In Fig. 10, a solid connection is produced by bending the edge of the upper plate around the extremities of the segments, or by holding the latter in a groove of the flanged upper plate. In Fig. 9, a second bottom plate is employed, which has at its center a perforation serving to guide the shank of the button. The edge of the second bottom plate is bent over the edges of the segments.

In Fig. 5 the edge of the top plate is bent down over the edges of the segments and of a second bottom plate.

In Fig. 11, the edge of a second bottom plate is bent over the edges of the segments and also over the edge of a cover plate, in a manner similar to Fig. 9. Fig. 6 shows a button composed of a first bottom plate as shown in Fig. 3', a cover plate as seen in Fig. 2, and a second bottom plate as seen in Fig. 4. This second bottom plate has radial cuts at the circumference which divide it into twelve or any other number of segments 1 2 3 4, 5 6 7 8, &c., which are turned on their bases, 3 4, 7 8, 11, 12, 850. By thus turning these segments in the manner indicated in dotted lines in Fig. 4, the diameter of the disk is increased from Z to the diameter Z of the circular groove of the upper plate or disk shown in Fig. 2. In this case the segments CL 1) c d, a b c d, &c., of the first bottom plate are placed between the top plate and the first bottom plate.

Fig. 8 represents a clothes button composed of an upper plate as seen in Fig. 2 and a lower plate as seen in Fig. 3. In this case the segments at b c d, 0. b c d, &c., of Fig. 3 are bent on their respective base lines 0 d, c d, &c., sufficiently for introducing them into the groove of the top plate (Fig. 2) as has been described with reference to Fig. 4, for the case of a second bottom plate. The supporting ring is cylindrical and serves as a guide or bearing for the shank.

With the exception of the form seen in Fig. 9, care must be taken to leave sufficient clearance that the head of the shank requires but slight pressure to pass through the opening formed between the ends of the segments e'fc' d, 6 f c d, &c., when the latter have been turned on their respective bases until their ends touch the top plate.

Having thus described my invention, What I claim is- 1. The combination of a bottom plate having a central perforation forming a bearing for the lower end of the shank, and having slits extending inward from its circumference, whereby two series of segments are formed therein, the said two sets of segments one of said sets of segments being bent inward to form a central bearing for the upper end of the shank and a cover plate having a groove with which the circumferential edges of the other set of said segments engage, substantially as set forth.

2. The combination of a bottom plate having a central perforation and a supportingring surrounding said perforation and adapted to form a bearing for the lower end of the shank, said plate being also provided with slits extending inward from its circumference whereby two sets of segments are formed therein, the said two sets of segments one of said sets of segments being bent inward to form a central bearing for the upper end of the shank, and a cover plate having a groove with which the circumferential edges of the other set of said segments engage, substantially as set forth.

3. The combination of a bottom plate having a central perforation and a supportingring surrounding said perforation and forming a bearing for the lower end of the shank, said plate being also provided with slits extending inward from its circumference whereby two sets or series of segments are formed therein one set of said segments being bent inward to form a central bearing for the upper end of the shank, a second bottom plate having a central perforation forming a bearing for the lower end of the shank, and a cover plate having a groove with which the circumferential edges of one of said bottom plates engage whereby said cover plate is held in place, substantially as set forth.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
